Does hydrogen peroxide help cavities?

I heard someone at work mention that rinsing with hydrogen peroxide can help with tooth problems. I'm wondering if it could be useful for cavities. Can hydrogen peroxide actually help with cavities or prevent them from getting worse?

No, it doesn't cure or reverse cavities at all. My dentist clearly explained that once the enamel has decayed and formed a hole, only a proper dental filling can fix it. Hydrogen peroxide might temporarily kill some surface bacteria, but it won't rebuild the lost tooth structure.

I tried rinsing with diluted hydrogen peroxide last year thinking it would clean out my tooth ache. Honestly, it did absolutely nothing for the cavity and just made my gums feel dry and irritated. I ended up having to get a filling anyway, so I'd say just skip it and see a dentist.

It is much better to focus on calcium-rich foods and reducing sticky sweets than using harsh chemicals like hydrogen peroxide. I make sure to rinse my mouth with plain water after eating any fruits or carbs. If you already have a cavity, chemical rinses won't dissolve the decay, you need professional dental help.

Unless you want your mouth to bubble up like a science project, please don't try this! It won't melt the cavity away, trust me. Better to spend that energy finding a dentist who doesn't make that scary drilling sound, haha.

I totally get it, dental visits can be really scary and expensive, so we look for home remedies. But hydrogen peroxide can actually burn the sensitive tissues inside your mouth if you are not careful. Please don't risk your gums, it is much safer to get a professional checkup.
